Commonly Asked Questions
1. The LED readout is constantly blinking. Why is that?
• The blinking LED indicates no connection. This can only occur if power was not supplied to either transmitter or
receiver modules. Please ensure you have both transmitter and receiver module power cables rmly attached.
• If still blinking, please check that your power supplies are working properly.
• Conrm the receiver is within range of the transmitter, ~100ft.
• Please contact Vocopro if problem persists or gets worse.
2. How many receivers can I have connected at once?
• You may have as many receiver modules wirelessly connected to the transmitter as you like. Any frequency change
performed on the transmitter will be communicated to all receivers currently linked.
3. A number of Vocopro wireless microphone systems have the same sized modules; can I install the Air-Net 2 into
there?
• No. The Air-Net 2 uses a different type of connector than any of our wireless systems. Please refer to Vocopro.
com for a complete list of compatible systems.
4. I’m missing some parts from my box. What do I do?
• Please contact Vocopro at 800-678-5348 regarding any missing or defective accessories.
RECEPTION
The Air-Net 2 uses the densely populated 2.4GHz frequency band. Home WiFi, cordless telephones and other consumer
devices also use the 2.4GHz band, which can potentially cause audible interference through the Air-Net 2. The maximum
operational range of the Air-Net 2 system is 100ft.
1. If you experience strange noises that do not sound like the audio being played, this may be indicative of frequency
interference. Try the following:
• Change the operational frequency of the transmitter to clear up the audio coming from the receiver.
• If range permits, lower the TX power level on the transmitter. This will lower the sensitivity in which interference
can occur. The higher the TX power, the higher probability of interference from other devices.
• Move both transmitter and receiver away from sources of 2.4 GHz signals such as WiFi routers and cordless
home telephones (cell phones do not apply).
2. If you experience loss of audio from the receiver, this means the connection between transmitter and receiver is
lost. Try the following:
• Keep the transmitter within range of the receiver, with respect to the TX power level. The maximum range of
100ft is achieved with the High TX power level selected.
• Elevate both receiver and transmitter module to ensure the wireless signal has a relatively clear line-of-sight,
especially at longer distances.
